Frequently Asked Questions

Q: Why should I replace my valves during a rebuild?
A: Even intake valves can wear or stretch over time due to high heat and frequency of cycling. Replacing them with high-quality ProX valves during a top-end refresh prevents compression loss and ensures that your engine continues to start easily and make full power.

Q: Should I also replace the valve springs?
A: Yes, it is highly recommended to replace valve springs and seals whenever installing new valves. Proper spring tension is critical to prevent valve bounce and potential contact between the valve and piston at high RPMs.

Expert Pro-Tip: After installing new valves, you MUST lap them lightly to the existing valve seat using a high-quality lapping compound. This ensures an air-tight seal for consistent performance. Always check your valve clearances after a short break-in period, as new valves can seat into the head slightly during their first few hours of operation.
